Increased vacuolation, cell enlargement and new cell wall deposition are the characteristics of cells in_____phase of growth.

Options

A. meristematic
B. elongation
C. maturation
D. differentitation

Answer

To determine the phase of growth characterized by increased vacuolation, cell enlargement, and new cell wall deposition, we can analyze the different phases of plant cell growth step by step.

### Step-by-Step Solution:

1. **Understand the Phases of Plant Growth**:
- Plant growth can be divided into three main phases: meristematic phase, phase of elongation, and phase of differentiation (or maturation).

2. **Identify Characteristics of Each Phase**:
- **Meristematic Phase**:
- Cells are actively dividing.
- Features include thin cell walls, dense protoplasm, and prominent nuclei.
- **Phase of Elongation**:
- Cells begin to grow in size.
- Characteristics include increased vacuolation (more vacuoles), cell enlargement, and the deposition of new cell walls.
- **Phase of Differentiation (Maturation)**:
- Cells have completed their growth and have specialized functions.
- Most cells lose their protoplasm and nuclei, and secondary walls are fully deposited.

3. **Analyze the Given Characteristics**:
- The question specifies increased vacuolation, cell enlargement, and new cell wall deposition.
- These characteristics align with the **phase of elongation**, where cells are actively growing and expanding.

4. **Conclusion**:
- Based on the analysis, the correct answer is that increased vacuolation, cell enlargement, and new cell wall deposition are characteristics of cells in the **phase of elongation**.

### Final Answer:
Increased vacuolation, cell enlargement, and new cell wall deposition are characteristics of cells in the **phase of elongation**.
